Forces forming a couple are of magnitude

12 {~N}

each and the arm of the couple is

8 {~m}

. The force of an equivalent couple whose arm is

6 {~m}

is of magnitude

View answer and explanation

Correct option: B

16 {~N}

Option B (

16 {~N}

) is correct because the moment of a couple is constant, so equating the moments of the two couples gives the unknown force.
